ALLETE Clean Energy Earns Yellow Ribbon Designation

Company recognized for supporting veterans, service members and their
families

DULUTH, Minn.--(BUSINESS WIRE)--
As Veterans Day approaches, ALLETE Clean Energy, an ALLETE Inc. (NYSE:
ALE) company, is proud to announce it has earned a Yellow Ribbon
designation from the state of Minnesota.

Overseen by the Minnesota Department of Military Affairs, the Beyond the
Yellow Ribbon program supports service members, veterans and their
families by connecting them with career counseling, professional
development and employment resources. The Yellow Ribbon program is a
sister program to Employer Support of the Guard and Reserve, a
Department of Defense program established to promote cooperation between
service members and their civilian employees.

To earn a Yellow Ribbon designation from the Department of Military
Affairs, companies must build relationships with local military leaders,
identify which employees have military connections and commit to hiring,
supporting and retaining veterans. The designation recognizes companies
that honor military-connected employees and their families, and
streamline their access to resources.

"Becoming the first clean energy independent power producer and
developer to be recognized as a Yellow Ribbon company illustrates ALLETE
Clean Energy's commitment to our military-connected employees, their
families and the communities in which we operate," said ALLETE Clean
Energy President Al Rudeck. "Military employees exemplify hard work,
dedication and a commitment to excellence that we all benefit from. I
thank all of our employees for their dedication to fulfilling their dual
role of military and civilian missions."

ALLETE and its subsidiaries have long supported military-connected
employees. Minnesota Power/ALLETE was named a Yellow Ribbon company in
2016, and ALLETE Clean Energy used Minnesota Power's experience as a
guide to quickly earn its certification. In September, the North Dakota
National Guard honored BNI Energy, an ALLETE company, in a Statement of
Support for the Guard and Reserve for encouraging employment of National
Guard members, Reservists and veterans.

ALLETE Clean Energy was established in 2011 to acquire or develop
capital projects to create energy solutions by way of wind, solar,
biomass, hydro, natural gas, shale resources, clean coal technology and
other emerging innovations.

ALLETE, Inc. is an energy company headquartered in Duluth, Minnesota. In
addition to its electric utilities, Minnesota Power and Superior Water,
Light and Power of Wisconsin, ALLETE owns ALLETE Clean Energy, based in
Duluth; BNI Energy in Bismarck, North Dakota; and U.S. Water Services in
St. Michael, Minnesota, and has an 8 percent equity interest in the
American Transmission Co. More information about ALLETE is available at www.allete.com.
